send data from client to specific server via unicast address

[michel_93]

Hi Guys,

We are currently working on a mesh sensor network. I have already developed a vendor sensor model (client and server). The client will also work as a gateway and will run on a nRF52840 DK. The Provisioner is on a separate DK just like in the Light Switch Example. The sonsors are a costum hardware with an nRF52840 on it.

The sensor send data on regular bases to the client via the mesh and the client then send it via UART to a computer.

During the provisioning process the nodes are picked randomly to add them to the network. Now the problem is that I have to know which device has received which unicast address.

I now want to send an On/Off message from the client to a unicast address and set an LED to identify which node it is. For that I have to change the publication address of the client locally. So is this possible without the provisioner? I have read that there is the following function available to change the publication address of a node: access_model_publish_address_set()

I found out that this function is in the access_config. h file decelerated but I haven't found a access_config.c file.

So which files do I have to include to use this functions?

Is there another way to change the publication address of a node locally?

Best regards,

Michel

You change the publication address like this: 

uint32_t status = NRF_SUCCESS;

  dsm_handle_t publish_address_handle = DSM_HANDLE_INVALID;
  nrf_mesh_address_t publish_address_stored;

  if (access_model_publish_address_get(m_clients[0].model_handle, &publish_address_handle) != NRF_SUCCESS) {

    status = dsm_address_publish_add(destination_address, &publish_address_handle);

  } else {

    if (dsm_address_get(publish_address_handle, &publish_address_stored) == NRF_SUCCESS) {

      if ((publish_address_stored.type == NRF_MESH_ADDRESS_TYPE_VIRTUAL) ||
          (publish_address_stored.type != NRF_MESH_ADDRESS_TYPE_VIRTUAL &&
              publish_address_stored.value != destination_address)) {
        /* This should never assert */
        NRF_MESH_ASSERT(dsm_address_publish_remove(publish_address_handle) == NRF_SUCCESS);
        status = dsm_address_publish_add(destination_address, &publish_address_handle);
      } else {
        /* Use the retrieved publish_address_handle */
      }
    } else {

      status = dsm_address_publish_add(destination_address, &publish_address_handle);
    }
  }

  switch (status) {
  case NRF_ERROR_NO_MEM:
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "NRF_ERROR_NO_MEM\n");
    //            status_error_pub_send(handle, p_message, sig_model, ACCESS_STATUS_INSUFFICIENT_RESOURCES);
    return;

  case NRF_SUCCESS:
    break;

  default:
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "ACCESS_STATUS_UNSPECIFIED_ERROR\n");
    //            status_error_pub_send(handle, p_message, sig_model, ACCESS_STATUS_UNSPECIFIED_ERROR);
    return;
  }

  NRF_MESH_ASSERT(access_model_publish_address_set(m_clients[0].model_handle, publish_address_handle) == NRF_SUCCESS);

destination_address is unicast address you want to send on/off command. You can figure out which header file you must include by searching the function on all solution.

Another method would be blinking led in provision completed callback on server.

Thanks for you answer. I will check it out this week.

Thank you very much the solution works

Can you share the data how you made this network. Basically I'm trying to build the sensor network using Bluetooth Mesh to transfer data to end node to computer.

Can you help me with your data to build the network.
